Session Log — Friday, April 17 2026

What We Worked On

  • NEO Trading Engine — FLAG-027 live verification (pre-run backup + preflight confirmed in real session start)
  • NEO Trading Engine — Session 31 (DB session 32) ran and completed (2h, ask=13)
  • NEO Trading Engine — Session 31 Segment B evaluation: VW +0.63 bps, FAIL
  • NEO Trading Engine — Atlas verdict on Phase 6B.2: revert ask=13 → 14
  • NEO Trading Engine — Capital injection planning ($50 available) → FLAG-030 and FLAG-031 identified and designed
  • NEO Trading Engine — Phase 7 VPS/infrastructure research (logged as FLAG-023)
  • NEO Trading Engine — End-of-session file updates: Experiment Log, Open Flags, CLAUDE.md, Atlas alignment files

What Was Built or Changed

  • [C] Atlas Alignment — Session 31 Evaluation + Phase 6B.2 Verdict.md — new, Atlas verdict logged
  • [C] Experiment Log.md — Phase 6B.2 section added (FAIL, revert decision, DB corruption notes)
  • [C] Open Flags.md — FLAG-027 marked VERIFIED AND ACTIVE; FLAG-029, FLAG-030, FLAG-031 added with full design specs
  • CLAUDE.md — Phase 6B status updated, config change required noted, capital injection sequence added, FLAG-027 verified
  • run_paper_session.py — FLAG-027 verified live (commit 9e124b4 from Apr 17 — backup/preflight/signal handlers)

Key Findings

  • ask=13 REJECTED: Two-session spread (S30 +1.29 PASS / S31 +0.63 FAIL) = no stability. Case 3: over-tightening. VW↓ + fills↑ — more fills converted at lower quality.
  • ask=14 is the right baseline. Phase 6A confirmed it. Phase 6B.2 confirms ask=13 is past the optimal point.
  • Capital injection blocked by two structural bugs: FLAG-030 (capital events not in inventory_ledger) and FLAG-031 (no profit/principal accounting). Both designed and ready for Orion to implement.
  • FLAG-023 (Phase 7 / VPS): Plan: Vultr/Linode $5-6/month, keep SQLite, upgrade QuikNode to dedicated ($10/month), two-wallet structure (trading + earnings). After Phase 6B closes.

Dashboard Changes (FLAG-028) — Committed + Pushed Apr 17

  • Read-only DB connection
  • Header col[5]: Realized Session PNL (spread_pnl)
  • Session PnL: Balances Row 2 + Execution Quality strip 4th tile
  • Threshold-based coloring (yellow for small losses, red for significant)
  • Sell/Buy Size Ahead: "—" when OFF_TOUCH
  • All PnL decimals standardized to 2dp
  • Refresh: 2s/3s options added, default 3s

Session 32 — Phase 6B Confirmation (Evening, Apr 17)

  • Config: ask=14, bid=10 (reverted from Session 31)
  • Fills: 44 total | buy=26 sell=18 | toxic=0
  • Segment B VW: +1.89 bps — PASS
  • Phase 6B: CLOSED ✅ Capital injection gate: OPEN

Evening / Late Night — Capital Injection + Scale-Up + Post-Injection Debug

Capital Injection Sequence — COMPLETE ✅

  • FLAG-008, FLAG-030, FLAG-031, FLAG-032 all resolved and merged to main
  • Injected 35.21 XRP @ 1.48 RLUSD/XRP | basis_delta: 52.1108
  • Post-injection wallet: 66.820 XRP + 97.610 RLUSD (~$197 total)
  • Live DB: net_basis_rlusd = 189.394878 | pnl_starting_value_rlusd = 191.57381667714765
  • Size raised to 15 (Atlas approved)

S33–S35 Post-Injection Issues — Diagnosed

  • S33: halted — max_xrp_exposure 100 too small for 76.92 XRP post-injection → raised to 150
  • S34: zero fills — buy_inventory_guard_blocked every tick (XRP-heavy, 57%) → raised max_inventory_usd 10→20 (turned out irrelevant — dead code)
  • S35: zero fills — buy_inventory_guard_blocked every tick even when RLUSD-heavy → escalated to Orion audit

Orion Audit Findings

  • No fills-only bug — all guards use total (post-overlay) InventorySnapshot
  • max_inventory_usd is dead config — comparison lives only inside a diagnostic log.info, no branch, no gate. buy_inventory_guard_blocked is a misleading label, not a real block
  • Zero fills = anchor-cap displacement — CLOB-AMM divergence was 20–23 bps; anchor_max_divergence_bps: 10 caused anchor to lag CLOB mid by ~10–13 bps
  • FLAG-034 confirmed — session summary shows fills-only XRP (41.71), not total (76.92). Fix designed, not yet committed
  • RLUSD headroom tripwire — max_rlusd_exposure 120 would halt engine after 2 SELL fills at size=15

Atlas Rulings

  • FLAG-034: APPROVED, implement
  • max_inventory_usd: RETIRE completely
  • anchor_max_divergence_bps: HOLD at 10, run one diagnostic session first
  • max_rlusd_exposure: APPROVED 150 (not 140)

Config — Final State (pushed ✅)

  • base_size_rlusd: 15.0
  • max_xrp_exposure: 150.0
  • max_rlusd_exposure: 150.0
  • anchor_max_divergence_bps: 10.0 (held)

Session 36 — Diagnostic Run (launched ~10:18 PM ET, running overnight)

  • Engine started clean, FLAG-027 backup confirmed
  • Startup reconciliation: 2 orphaned orders both filled (BUY +5.4 bps, SELL +18.6 bps)
  • CLOB-AMM divergence: -7 to -10 bps (regime flipped — anchor cap not binding)
  • First live tick: BUY filled within seconds (+2.04 bps)
  • Engine healthy, fills flowing

Git Rule Added

  • All git commands run in Katja's VS Code terminal. Vesper/Orion provide copy-paste commands only. Never touch repo via mounted filesystem — that path is unreliable for git operations.

Still Open

  • S36 running overnight (2-hour session). Review results in morning
  • Orion cleanup not yet in repo — FLAG-034, max_inventory_usd retirement, FLAG-033, FLAG-028 design complete and Atlas-approved, but commits not actually landed. Engage Orion next session to implement
  • Atlas Case A decision pending — if S36 fills still weak → widen anchor 10→15 bps

Start Here Tomorrow

Review S36 session results (fill conversion, VW spread, anchor vs CLOB gap). If fills are healthy → scale validation on track, engage Orion to commit the cleanup branch (FLAG-034, max_inventory_usd retirement, FLAG-033, FLAG-028). If zero fills → Case A applies, consult Atlas on widening anchor to 15 bps.
